Minnesota Vikings left guard Steve Hutchinson and cornerback Asher Allen are recovering from concussions.
Hutchinson cut open his lip and needed stitches after leaving during the third quarter. Coach Leslie Frazier didn't mention the concussion after the game but said Monday that Hutchinson must pass the league's required protocol this week to be cleared to return.
Hutchinson has started every game in nine of his 11 NFL seasons. He missed 12 games because of a broken leg in 2002 and the last five games of last season with a thumb injury.
Allen suffered a concussion during the first quarter against the Saints and safety Jarrad Page is day to day after injuring his hamstring, just the latest in a long string of injuries in the team's secondary. Two other starters -- cornerback Antoine Winfield (clavicle) and safety Husain Abdullah (post-concussion symptoms) -- have been placed on injured reserve, while cornerback Chris Cook is on the roster but not with the team as he deals with off-field legal issues.
